The Main Mpeg IC is ES8398ASA. SDRAM IC is M12L64164A. AMP IC is TAS5342.
The Main Mpeg controls each IC in this PCB.
Audio signal is come from CD Mecha, TUNER, AUX, MIC, BT.
Then MPEG IC encode them and sent them to AMP IC.
This signal go to the Crystal Amplifier(TAS5342). And amplified signal is Low Pass Filtered. This signal is real audio signal.
